1 Claim. 1

This invention relates to improvements in chases for printing pressesand the like and is directed more particularly to improvements inmechanism for locking type forms, electrotypes and the like in placewhere the same occupy less space than the open space in the chase.

We are aware that it has been attempted to lock type or the like inplace in a chase which occupies less space than the opening in the chasebut mechanisms of the prior art include members that engage with thechase members or parts of the mechanism interlock or fit with the partsof the chase. This makes it necessary not only to provide a chase ofspecial form which is costly but the interfitting parts determine inwhat portion of the chase opening the type must be located which isobjectionable. And prior art mechanism may only be used with chaseswhich are formed or arranged for the use thereof.

According to this invention, means is provided which may be used withany prior art or standard chase thereby eliminating the necessity ofchases having special forms for cooperating with the mechanism.

Various novel features and advantages of the invention will be observedfrom the following description of the form of the invention at presentpreferred.

In the drawings:

Fig. 1 is a plan view of a chase having the novel features of theinvention associated there with;

Fig. 2 is a perspective view of the transverse members forming a part ofthe mechanism of the invention; and

Fig. 3 is a perspective view of a longitudinal member of the invention.

Referring now to the drawings more in detail, the invention will befully described.

A chase is represented by 2 which has longitudinal side members 4 andtransverse end members 6 secured together to provide the usual opening.

A longitudinal member 3 preferably of metal is provided which may extendbetween the end members of the chase.

A pair of transverse members I!) are of a length to extend between thelongitudinal members 4 of the chase. These have on their lower sides aplurality of grooves l2 which are formed to snugly receive thelongitudinal member 8.

When it is desired to lock a type form such as M in the chase thelongitudinal member 8 is placed in the chase which is placed on a tableand the transverse members I U are located thereover with certaingrooves thereof receiving the member 8.

The ends of the members 8 and I0 although adjacent the longitudinal andtransverse members of the chase are not connected thereto. In this waythe members In may be located at any point longitudinally of the members4. Likewise the member 8 may be located at any point transversely wherethere are grooves in the members ID. This makes it possible to locatethe opening for the type form It Where desired in the chase opening, anda chase of special form is not necessary.

The type form I 4 has adjacent sides against adjacent portions of themembers 8 and i0 and blocking I6 is located between the members iii andend members 6 of the chase, preferably near the ends of the members I0.

The blocking l6 limits separating movements of the members l0 and otherblocking I8 and 20 is located against the member I!) at the ri ht andmember 4 of the chase. Keys or quoins 22 are located between theblocking I8 and 2B and the type form l4. These keys are of usualconstruction and are operated in the usual way to expand and exertpressure between the type form and adjacent parts.

The members II] are held against movement by the blocking I6 and themember 8 is held by the said members In so that the type form is lockedagainst the adjacent portions of the members 8 and Ill,

The invention may be embodied in other specific forms without departingfrom the essential characteristics thereof. Hence, the presentembodiments are therefore to be considered in all respects merely asbeing illustrative and not as being restrictive, the scope of theinvention being indicated by the appended claims rather than by theforegoing description, and all modifications and variations as fallwithin the meaning and purview and range of equivalency of the appendedclaim are therefore intended to be embraced therein.

What it is desired to claim and secure by Letters Patent of the UnitedStates is:

The combination of a chase formed by secured together transverse end andlongitudinal side members each having vertically disposed fiat innerfaces providing a central type opening of a certain size and havinginner continuous unbroken vertical faces with means cooperatingtherewith to provide a. relatively smaller type opening comprising, apair of transverse members extending between said longitudinal sidemembers hav- 3 o ing parallel unbroken longitudinal sides and fiatopposite end faces in sliding engagement with the unbroken inner facesthereof and provided with spaced aligned grooves having parallel andopposite side faces in parallelism with the inner vertical faces of thelongitudinal side members for receiving and holding a longitudinalmember against movement transversely of the chase, a separatelongitudinal member having parallel opposite side faces receivable inthe aligned grooves of the transverse members and having fiat oppositeend faces in engagement with the unbroken inner faces of the transverseend members, type blocking members between opposite ends of saidtransverse members and adjacent transverse end members of the chase andspacing said transverse members from said transverse end members andpreventing separating movements of the transverse members, saidtransverse and separate longitudinal members in cooperation with alongitudinal side member of the chase forming said smaller type opening.
